1001 Chess Exercises for Beginners by Franco Masetti and Roberto Messa is a popular tactical workbook designed to build board vision and pattern recognition. While the PGN (Portable Game Notation) version of this book is often used in digital training platforms like Chessable or via interactive Lichess studies , the core content is organized into specific tactical themes.
